He didn't ask for an amount or a minimum or even specify a length of time to go back. In the end, it was all for nothing. He (and his boss) never saw them.
My entry history was never mentioned. Not even in passing. If it played a role, I wouldn't know.
I had some Exempt entries and SETVs, did a one year ED visa which I got in Vientiane September 2018. Went to visa exempt while waiting for enough students to sign up for or finish the beginner level. (Rolling starts to the program.)
Now I applied for my second ED visa to learn Thai at Vientiane.
I'll add this to the main post: I never talked to an immigration officer. I was expecting a man in his 50s, gold-rimmed glasses, in a uniform with badges and a name tag.
I never got to state my case. I was prepared to be interviewed.
Why do you want to stay in Thailand?
Why do you want to study Thai language?
What do you do for work?
How do you support yourself?
And expected to be quizzed in Thai. Maybe asked to write my name or something. I don't know.
